Pelty is a Bluetooth speaker that's powered by candle flame

  1. The concept of using one of humanity's oldest resources - fire - to generate electricity is nothing new. Innovative projects like the BioLite BaseCamp Stove, which uses a thermoelectric generator to transfer heat from fire into usable electricity to power...

    How is it in any way practical? Especially in the light of solar panels coming everywhere, it seems utterly useless. Need to light a candle to hear the sound - that's just insane.

    They would better make a converter from heat to electricity. For example, if you go camping, you could make a fire and throw it in to recharge something.

    So instead of burning a small candle, we would be aiding in the destruction of what little forest we have left. I mean if we buy a device that will produce electricity by fire, might as well use it everyday. Next thing you know we will be powering our air-conditioners by outside fire. lol

    I was thinking more of a post-apocalypse scenario, at least to have some electricity from the world burning ;)
  5. That's it, I'm tossing out my gas heater and lighting fires in the house, like the middle of each room, and then I'm going to hang electrical devices over the top.

    That would be one hell of a camping trip!

    Bluetooth powered by candlelight?
    sold! (to those romantic people who enjoy candle-lit dinners.)

    I consider myself leaning towards the tree-huggers so I dislike any tech that tends to produce more carbon emission.
    for 'green econo-environment' efficiency purposes, the 'pelty' creators could have chosen electricity powered by air/wind (and not by farts. :) )

    Guys I think you are missing the point.
    Pelty is not about blackout or apocalypse. It's a device willing to create the right atmosphere for your special occasion, moment of relax; it's original and in the eco-friendly argument please consider that it's made in ceramic and glass, 100% natural, not in plastic.
    Also, it's hand made, not produced in some chinese factory.

    I like to see and hear it belt out The Doors old hit 'Light My Fire'. It could become a hit once again.
  11. Guys I'm thinking bigger, their is enough heat coming from my PC CPU and GPU that maybe one day it could power itself! At the very least reduce my electricity bill.

    Here's hoping!!

    I wouldn't shell over US$200 for this, when I have a solution for a tenth of the price and it just charges over a usb port.

    If it were cheaper it might be... colorful to say something but totally impractical.

    Ok let's add to the survival thingie, now you have a candle light speaker, what are you going to play? Your dead phone? Your "cassette" player? IMPRACTICAL.

    If they were creating a charging station powered by a candle I would totally dig it, since that is not the case and the price tag is a joke... *flies away*

  13. We need this to power a post apocalypse WAN with a copy of the internet. Internet forever!

    I can't picture a candle-lit speaker providing rock-concert like sound. So what levels of sound will come out of that thing? 50 dB? 60 dB? And will that sound be of an acceptable quality?

    Fixed that for you as rock music would be more likely to cover up bad qualities in a speaker. As much as I really don't like slow music, slow music would be the best for use when testing speaker quality. Much the same way as your eyes needing time to focus on picture differences. If the picture changes to quickly, you would not likely notice the differences.

    But then you also have the thought. How on earth could you ever get concert like sound, if you are not in a concert hall? So I really should cross out concert as well and replace it with another term. Another term that is more likely achievable, such as the original term "rock-concert".
  16. Very innovative invention. This helps lessen consumed electricity just by replacing it with candle flames. Brilliant idea!

    Well, you do understand you're supposed to turn the blue tooth OFF during said candlelight dinner, don't you?

    Using the dinner candles to power up your phone sounds really, really counterproductive to getting lucky afterwards.

    Be ready to hear, "not now dear, I have a phone call".:'(

    Actually, one of the most difficult tests of audio equipment in general, and loudspeakers in particular, is accurately reproducing acoustic piano.

    Answer, you can't. Surely, some little trinket with a headphone size driver won't really produce any type of "concert sound", in any capacity, with respect to frequency response, volume, dynamic range, or ambiance.

    Here are recounts of some epic moments in permanent hearing damage:

    The PA systems of those events were probably in the neighborhood of 75,000 watts RMS.

    It would be interesting to sit down and try to figure out how many candles you'd have to light for that kind of output.
